Front and Rear.... I was going to shoot for 32 and 34 but trying to get close and save a session. What do you guys normally see increase wise? Was thinking of starting at 27 and 29.

Morning temps at VIR should be in the low 70s....

Thank you!

I usually gain 12 pounds. But some only gain 8 or 10 of pressure when fully hot. I also only want the rears 1 pound more than my fronts. With cups 33 front 34 rear hot

26. Bleed as required.

I try to run 34 hot all around.

Great info, thanks. Little less oversteer with 34 front and rear? Any other subtleties?

Get a good alignment. My car has always been pretty neutral.

Learn to throttle steer if you don't already. The car responds to subtle movements of the throttle to transfer weight to and from the front tires.

25 cold and 35 hot. I typically do 35 all around and/or 1 pound less in the front.

You guys must be a lot faster/moving the car around mre than I am. I was only seeing 4-5 psi total gain from cold to hot. I was only seeing 32ish because I kept thinking they would gain more. Added more air and finally hit 34 on the last session.

There is usually more than one 996 GT3 on any given track day. Pull out a stop watch and see what their times are like compared to yours. If there is more than 2 seconds then get instruction. That is the fastest way to progress.
